MTC Bio SureSeal S™ C2000 | 1.5mL Microcentrifuge Tube with Attached Cap, Clear, Sterile — 500/Pack

Product Description

The MTC Bio SureSeal S™ C2000 is a 1.5mL sterile microcentrifuge tube with attached cap — manufactured in a clean room from BioClear™ co-polymer, a proprietary advanced polypropylene that delivers exceptional optical clarity, centrifugal strength up to 28,000 × g, and an operating temperature range of -90°C to +121°C. MTC Bio's SureSeal S™ microcentrifuge tubes are designed for a broad range of research applications, including enzyme digests, DNA isolation/purification, centrifugation, incubation, and general sample/reagent storage. San Every pack includes a self-standing gusseted bag for stable benchtop organization and 10 Stop-Pops™ cap locks per bag. Sterile by electron beam radiation. RNase-free, DNase-free, and pyrogen-free. 500 tubes per pack. Available in clear and a full range of individual and assorted colors.

BioClear™ Co-Polymer — Crystal Clear, Maximum Strength, Maximum Temperature Range The BioClear™ co-polymer is the material technology at the heart of the SureSeal S™ — a proprietary advanced polypropylene specifically formulated to deliver three performance characteristics simultaneously that standard polypropylene cannot match at once: BioClear™ has been formulated to be crystal clear, without compromising centrifugal strength (tested up to 28,000xg) or the usable temperature range (-90°C to +121°C). Standard polypropylene microcentrifuge tubes trade off clarity for strength or strength for temperature range — BioClear™ eliminates these tradeoffs, providing the optical clarity of a premium tube with the mechanical and thermal performance of a heavy-duty tube.

28,000 × g Centrifugal Strength — Tested, Not Estimated The C2000 is tested to withstand centrifugal forces up to 28,000 × g — well above the maximum speed of virtually all standard laboratory microcentrifuges (typically 16,000–21,000 × g). The tested 28,000 × g rating provides a meaningful safety margin across all standard microcentrifuge applications including high-speed pelleting, spin column protocols, protein precipitation, and any centrifugation step requiring maximum speed without concern for tube failure.

-90°C to +121°C Operating Range — From Liquid Nitrogen to Autoclave The exceptional -90°C to +121°C operating temperature range of the C2000 covers the complete spectrum of laboratory temperature conditions in a single tube format — from ultra-low temperature storage in liquid nitrogen (-196°C submersion uses cryogenic tubes; -90°C covers dry ice and -80°C freezer storage) through standard -80°C, -20°C, and 4°C refrigerated storage, room temperature incubation, 37°C and 65°C water bath incubation, and autoclave sterilization at 121°C. A single tube type handles every temperature stage of the most complex workflow without format changes.

Ring & Groove Closure — Liquid-Tight Seal with Ergonomic Locking Force The oversized tube cap (with frosted marking surface), combined with the unique ring & groove closure, enhances the security of the liquid-tight seal, while minimizing the required locking forces for a more ergonomic opening/closing of the tube caps. The ring and groove interlocking mechanism of the SureSeal S™ closure creates a positive mechanical engagement between cap and tube — forming a liquid-tight seal that prevents accidental opening during centrifugation, vortexing, inversion, and transport. The engineering optimization that reduces the locking force required to open and close the cap is specifically designed for the ergonomic demands of high-throughput labs where tubes are opened and closed hundreds of times per day — reducing hand and finger fatigue compared to tubes with unnecessarily high cap locking forces.

Oversized Cap with Frosted Marking Surface — Easy Labeling, Easy Identification The oversized cap of the SureSeal S™ provides more surface area for labeling than standard microcentrifuge tube caps — making it easier to write clearly with permanent markers and to read labels at a glance in tube racks, ice buckets, and centrifuge rotors. The frosted surface on the non-graduated side of the tube provides an additional labeling area — and accepts permanent marker, pencil, and cryogenic label adhesives — for comprehensive sample identification on both cap and tube body simultaneously.

Syringe-Permeable Cap — Through-Cap Injection Without Opening Syringe Permeable Cap - 2mm circle is thinner, allowing through-cap injection. The SureSeal S™ cap features a 2mm thinned circle on the cap surface that allows direct needle injection through the cap without removing it — maintaining the sealed sterile environment while allowing reagent addition, sample withdrawal, or gas exchange through a needle. This is particularly valuable for protocols requiring aseptic addition of reagents to sealed tubes, for radioactive or hazardous sample handling where maintaining a closed system is a safety requirement, and for automated liquid handling systems using through-cap needle access.

Stop-Pops™ Cap Locks — 10 Included Per Bag Stop-Pops™ supplied – 10 cap locks in every bag. Stop-Pops™ are MTC Bio's proprietary cap lock accessories — small plastic clips that physically lock the tube cap closed, preventing accidental opening during vortexing, centrifugation at high speeds, or transport. Ten Stop-Pops™ are included in every 500-tube bag — providing immediate access to cap lock protection for the most critical samples in every pack without requiring a separate accessory order.

Self-Standing Gusseted Bag — Organized, Accessible Tube Storage Self-Standing bag – with gusseted bottom. The gusseted bottom of the self-standing bag allows the 500-tube bag to stand upright on the benchtop without tipping — keeping tubes organized, accessible, and protected from contamination throughout use. The self-standing format eliminates the frustration and contamination risk of a collapsed bag tipping and spilling tubes across the bench.

Clean Room Manufactured — Sterile by Electron Beam Radiation SureSeal S tubes are manufactured under clean room conditions. Sterility is achieved by electron beam (e-beam) radiation — a highly effective sterilization method that provides sterility assurance without the heat damage or residual chemical concerns associated with ethylene oxide sterilization. E-beam radiation sterilization is the method of choice for premium laboratory plasticware requiring the highest sterility standards.

Available in a Full Range of Colors — Individual and Assorted The SureSeal S™ 1.5mL tube is available in a complete range of individual colors and assorted packs for color-coded sample organization:
